Abstract

A power unit is provided which can perform stable feedback control by reducing a feedback gain, and sufficiently cope with fluctuations in the output voltage occurring according to fluctuations in the input voltage caused by fluctuations in the rotational speed of an engine. A pair of variable control bridge circuits are connected to three-phase output windings of a three-phase generator driven by the engine, and connected in an antiparallel manner to each other to form a cycloconverter for generating a single-phase alternating current to be supplied to a load. An effective voltage value-detecting circuits detects an effective value of a voltage of the alternating current. A reference effective voltage value-generating circuit generates a reference effective voltage for controlling the single-phase alternating current. A target wave-forming circuit forms a target wave for making the effective value of the voltage closer to a value of the reference effective voltage. A firing angle control device performs switching control of the variable control bridge circuits, based on the target wave, such that the variable control bridge circuits are alternately switched to operate every half a repetition period of the alternating current. A rotational fluctuation-detecting circuit detects fluctuations in a rotational speed of the engine in a rotation cycle thereof. A gain-adjusting circuit generates a reverse characteristic signal having a characteristic reverse to a characteristic of the fluctuations in the rotational speed of the engine.
A comparator corrects amplitude of the target wave based on the reverse characteristic signal.
